WINDOW VENTILATOR.

AppIication filed January 5, 1921. Serial No. 435,134.

To aZ-Z whom it may concern Be it known that 1, DANIEL J. MURNANE, a citizen of the United States, residing at Chicago Heights, in the county of Cook and State of Illinois, have invented a new and useful Improvement in vVindow Ventilators, of which the following is a specification.

My invention relates more particularly to ventilators of the type employing a platelike portion, either rigid or flexible, which is positioned on the inside of a room, adjacent the window sill of a window and in spaced relation to the window sash, thereby to afford,,when a window is partially raised, a deflecting surface which serves to cause the air entering the window to be deflected upwardly into the room and thereby avoid drafts.

My primary objects are to so construct the device that, when not in use, the parts thereof may be caused to occupy a position in which they are out of the way and will pre sent a sightly appearance, and be readily moved into operating position; to provide a construction of such device that it may be manufactured economically and shall be simple of structure; and other objects as will be manifest from the following.

Referring to the accompanying drawings:

Figure 1 is a face view, taken from the interior of a room, of a window in the wall thereof, showing it as equipped with a ventilator embodying my invention, the central portion of the structure shown being broken away. Figure 2 is an end view of the structure shown in Fig. 1, this view being taken from the right hand side of Fig. 1. Fig ure 3 is a section taken at the line 3 on Fig. 1 and viewed in the direction of the arrow; Figure 4 is a section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow; and Figure 5, a broken perspective view of one end of the upper portion of a curtain employed in the structure of the fig ures now being described.

Referring to the construction shown which illustrates the preferred embodiment of my invention, a window-frame of i a window to be equipped with the device is represented at 11, the lower sill of which is shown at 12, there being mounted within the frame 11 to slide up and down therein, a window sash 13 containing the glass pane 14.

The particular structure of ventilator shown is formed of plates arranged to be located at opposite sides of the windowframe 11 andextend, when in operating position, at angles thereto and into the room, each of these plates'being formed of sections 14 and The sections 14 which are shown as being permanently secured to the windowframe to extend inwardly therefrom, are

shown as of general rectangular shape having cars 16' stamped from the metal there'- of, and together with the rearwardly-extending portions 17 of these plate sections, fit over the corner of the adjacent uprights of the window-frame, the plate-sections being shown as rigidly secured in such position by means of screws18 and 19. The 14 preferably fit, closely plate-sections against the top side of the window sill 12, and preferably extend a slight distance inwardly therefrom as shown. The plate-sections 15 are shown as of general triangular shape with their upper edges curved as represented, the plate-sections 15 being hingedly connected-with the plate-sections 14, as

through the medium ofthe hinges represented at 20 and secured to these respective sections, the hinges being of such construction that the plate-sections 15 may be swung on the plate-sections 14 to extend adjacent, and in generally parallel relation, to the adjacent uprights of the window frame 11. In

other words, the plate-section 15 at the right hand side of Fig. 3 may be swung'in counter-clockwise direction to extend generally parallel with the sill 12, and the plate-secrepresentedv at 21, these channels opening toward each other. Bars 21 are pivotally connected at their lower ends, asthrough the medium of the pivot pins 22, with the adjacent plate-sections 14, the upper ends of these bars being' provided with outwardly-turned ends 23 which extend over the upper edges of the plates referred to and overlaptheir outer'sid'es, being spaced therefrom sufficiently to' permit of the swinging of these bars on their pivots for a purpose hereinafter described. The portions 23 are connected by a pin-and-slot connection with the outer ends of levers 24 located at the outer surfaces of the plates referred to and pivotally connected at 25 with the stationary plate-sections 1a, the pinand-slot connection shown comprising, as to each of the connections, a pin 26 on the bar portion 23 and a slot 27 in the adjacent lever 24 into which the pin 26 extends.

It will be understood from the drawings and the foregoing description that the bar and lever structure just described, serves as a means for holding the plate-sections 15 and 14 in aligned condition and against relative swinging movement, when the bars 21 are swung outwardly to the position shown in the drawings, in which position, it will be noted, these bars and levers extend across the joints between the platesections, and when these bars and levers are swung toward the window, to a position in which they extend substantially vertical and are out of a position in which they overlap the sections 15, the latter are free to swing on their hinges 20 in the respective directions hereinbefore described, by reason of the action of the springs in the hinges.

In the particular construction illustrated the bars 21 serve as a swinging holder for the front, or deflecting side 28 of the ventilator, which may be, and preferably would be, a pane of glass, mounted in a frame, or not, as desired, the deflecting surface 28 extending at its ends into the channels in the bars 21, and, by reason of the arrangement of the bars, as hereinbefore described, being readily movable from deflecting position, represented in Fig. 2, in which position the pins 26 are shown as engaging the outer ends of the slots 27, to a position in which it extends substantially vertically closely adjacent the window. It would be preferred that the deflecting surface 28 be of transparent material because, in accordance with the preferred embodiment of my invention, this section would remain operaatively connected with the window-frame, when not being used as a deflector surface.

It will be understood from the foregoing that when the parts are in the position shown in the drawings and the window 14: is raised, preferably not above the upper edge of the deflector surface 28, the air passing through the open portion of the window will strike the deflecting portion 28 and thereby be deflected upwardly into the upper portion of the room.

The device now being described, is also provided with a curtain device involving the use of a flexible sheet rolled upon a circular roller represented at 29 and journaled at its ends in brackets 30 secured to the window frame below the window sill 12.

and shown of hook form adapted to hook over inwardly-turned flanges 84 on the outer edges of the plate-sections 15. The curtain 31 is of such width, that when it is upwardly drawn on at its free edge portion to partially unroll it, it will extend adjacent the upwardly-inclined edges of the plate-sections 15, the curtain being held in such position, in which it extends in an upwardly-inclined direction from the window toward the center of the room, by the en- 1J1 gagement of the hook portions of the clips with the upper edges of the flanges 23% as stated.

In practice the device may be provided with both the deflecting section 28 and the curtain 31 permitting the user to use either one of these portions as a deflecting surface, as desired either by reason of possible impairment of one, or as a matter of choice, or employing the curtain section as a means of obstructing the view through the lower portion of the window in which case the curtain would be of opaque material. ll? desired, the section may be of opaque ma.- terial to obstruct the view through the lower part of the window, and where it is desired to have the section 28 of transparent material, the use of the curtain 31 would be quite desirable especially where the device is installed in dwellings.

While the two portions 8 and 31 may be used, under some conditions, to advantage in the same structure, it will be understood that so far as certain features of the struc ture are concerned the deflecting surface 28 or the surface 81 may be omitted, and where the portion 28 is omitted the curtain 31 would form the air-deflecting surface. iVhen the curtain 31 is not in use it would assume the rolled condition represented in i Fig. d and by reason of its location, it is more or less obscured from View.

The provision. of the bars pivoted to the plate-sections 14 at points above the pivotal support of the bars 21 is of advantage as thereby the hinged plate sections 15 are firmly braced in extended position.

While I have illustrated and described a certain particular construction in which my invention is embodied, I do not wish to be understood as intending to limit my invention thereto as the invention may be embodied in other structures, and the structures as shown may be modified and altered without departing from the spirit of my invention, it being my intention to claim my invention as fully and completely as the prior state of the art will permit.

What I claim as new and desire to secure by Letters Patent is:
